135 - Lightweight Merino T-shirts

The 135-series are high performance lightweight merino wool t-shirts. They are thin & light, making you feel like wearing nothing. They efficiently keep you tempered indoors and in hot environments, and are still comfortable when the temperature drops, even if you are sweaty.

They are highly wearable indoors and under shirts and suits. Available in 6 neutral colors, developed to match a broad variety of clothes and activities.

220 - Heavy Duty Merino T-shirts

Our 220 T-shirts are heavier, more durable and provides more insulation. They are less fitted than our 135 T-shirts and great for colder weathers and demanding conditions. 

135 Limited

Unique colors and designs. Made once in limited quantities, available until sold out.



Newline and LOOW were both founded by Danish Special Operation Forces operators and share the values of attention to details, quality and durability.  Both tees can be worn as a first inner layer or simply as a tee for all kinds of training.

Merino wool Accessories

Our hearts are beating for T-shirts, but upon request we have made a serie of  accessories, so you can enjoy the benefits of merino wool from top to toe.


We recommend not using regular washing detergent, as it breaks down the wool fibers.
Using a wool detergent containing lanolin will preserve the abilities of merino wool and provide for a longer lifespan.
